(loosely) A contradiction in terms. Historically, an oxymoron was a paradox with a point, where the contradiction seems absurd at first glance, and yet is deliberate, its purpose being to underscore a point or to draw attention to a concealed point.
By far the most massive planet in our solar system, Jupiter features giant hurricanes, auroras, abstract artistic cloudswirls, and maybe even a solid core. It also protects Earth by gravitationally clearing the solar system of asteroids and comets.
Jupiter, which is 318 more massive than Earth, is less dense because it is made of gases, such as hydrogen. Earth's mass is 6.6 sextillion ton (5.9722 x 10 24 kilograms). It volume is 1.08321 x 10 12 km. The total surface area of Earth is about 197 million square miles (509 million square km). About 71 percent is covered by water and 29 percent by land.
